Comparison of the Wilson depression derived from the divergence method and the pressure method for AR 10923. Panel A: Wilson depression derived using the pressure method and panel B: Wilson depression derived using the divergence method. The black and white contours indicate the outer and the inner penumbral boundary, respectively. The dashed black contour shows the region that was used for defining zW = 0 (distance of at least 7 Mm to the sunspot). Bottom panels: Wilson depression along cuts across the sunspot (marked by the dashed lines in the top panels). Panel C: a cut along the x-direction, panel D: a cut along the y-direction. Black: Wilson depression inferred from the pressure method, red: Wilson depression inferred from the pressure method degraded to the spatial resolution of the divergence method, green: Wilson depression derived using the divergence method.
